.SH DESCRIPTION
.sp
.LP
The \fBinitscr()\fR function initializes X/Open Curses data structures,
determines the terminal type, and ensures the first call to
\fBrefresh\fR(3XCURSES) clears the screen.
.sp
.LP
The \fBnewterm()\fR function opens a new terminal with each call.  It should be
used instead of \fBinitscr()\fR when the program interacts with more than one
terminal.  It returns a variable of type \fBSCREEN\fR, which should be used for
later  reference to that terminal. Before program termination, \fBendwin()\fR
should be called for each terminal.
.sp
.LP
The only functions that you can call before calling \fBinitscr()\fR or
\fBnewterm()\fR are \fBfilter\fR(3XCURSES), \fBripoffline\fR(3XCURSES),
\fBslk_init\fR(3XCURSES), and \fBuse_env\fR(3XCURSES).
.SH RETURN VALUES
.sp
.LP
On success, the \fBinitscr()\fR function returns a pointer to \fBstdscr\fR;
otherwise, \fBinitscr()\fR does not return.
.sp
.LP
On success, the \fBnewterm()\fR function returns a pointer to the specified
terminal; otherwise, a null pointer is returned.
.SH ERRORS
.sp
.LP
None.
